基于分子动力学的有机朗肯循环Cu/R123纳米有机工质能量研究
Energy analysis of a Cu/R123 nano-organic working fluid based on molecular dynamics in organic Rankine cycle
摘要
Abstract
To investigate the energy variation characteristics of the Cu/R123 nano-organic working fluid in organic Rankine cycle(ORC),molecular dynamics simulations were conducted to analyze the energy behavior of the Cu/R123 nano-organic working fluid under different operating conditions.The results indicate that the addition of nanoparticles can alter the microstructure of the organic working fluid.Specifically,in a microscopic state,van der Waals energy decreases with increasing volume fraction,bond energy increases with rising temperature,van der Waals energy increases in gas phase,and pressure has minimal impact on the system.Furthermore,calculation of enthalpy difference reveals that at equivalent evaporation temperatures,ORC using nano-organic working medium performs more work.Additionally,it is observed that nano organic working medium exhibits high thermal conductivity which can enhance low-grade heat recovery efficiency of the ORC.关键词
